Initially disk boot failure now White screen but runs in oter mon
I tried to restart my PC after 6 months, initially it showed disk boot failure, then after few trials of power on/off it booted and worked for a day. But the next day onwards that method is not working on the contrary the screen(Acer 17"LCD)goes to white screen for few minutes then to black screen (initially starts with some horizontal lines) .
I opened and reassured the tight connection of hard disk, then checked with friends monitor and its works fine. But not with my monitor.
Above all I am feeling a mild shock while touching the PC casing, is there any connection?
My question shows my ability, please do help me.

Try checking inside the computer for loose wiring near where the power supply box plugs into the motherboard, make sure that you turn the computer off and remove it from the outlet before opening it. While the computer is open, check all of the leads going into the motherboard are pushed in gently but firmly. Remove the RAM clean it with a soft paintbrush and then return them to there slots ensuring that they are seated correctly. Do the same with the graphics card and sound card if you have them in PCI slots or AGP slot returning them correctly into thier slots.
Put everything back together and before powering back on make sure that the power leads going into your PC and into your monitor have not been damaged in any way. Reboot your computer and try again. If you still get a shock or your computer does not boot properly then you may need to change the power supply box.

The computer can not see the Operating System. This can be caused by several things, so I will just list a few possiblities for you here:
If you have a USB flash drive or external HD plugged into the PC. Remove it while the computer boots. Some machines are set to boot from a flash drive and will search for an operating system on it and display NO OS if the bios can not find one.
If the Hard drive has been removed or replaced recently then the Jumper settings may not be correct on the new drive.
If the computer was having trouble booting periodically, freezing or experiencing blue screens before this message, then you may have HD corruption or possible disk failure. With HD corruption you only need to run chkdisk /p within recovery console in XP or run the Vista recovery center with vista. HD failure is a dead disk, no option but to replace.
Bad RAM or a dead CMOS battery can also cause this type of failure. So check these also.
This can also be caused by a damaged master boot record or primary boot partition. Run fixboot or fixmbr from the recovery console on XP or just run the Vista Boot Repair Console in Vista
Worm Viruses and Rootkits that damage the primary boot sector or the Master Boot Record can also cause the OS to mysteriously disappear. So if none of the above sound like they are for you, then you can try looking for one of these on the affected drive.
You might need to change the screen refresh rate. Go do Control Panel> Display> Setting> Advance, choose 60 Hz. In order to make your Monitor able to display, restart the PC, press F8 on the keyboard frequently upon splashing ( 1 or 2 seconds after PC restarts). Select enable VGA mode by pressing up arrow of the keyboard> press enter. The display should look bigger, then you can start adjusting the screen refresh rate to 60 Hz
johnerm, Good going John! At least YOU tried doing a swapout to another KNOWN GOOD pc to prove out that the E153FP is indeed the culprit!!! Now for the hard part. Do you have a bright flashlight? Reconnect E153FP to pc with WIN-desktop as the displayed image. then and only then turn on E153FP and note the time it takes to GO TO BLACK SCREEN. Is it 1, 2, --5,---20 seconds???? Now point at different angels about 1 inch from screen a bright flashlight to an area that "should" have a desktop "icon" showing. LOOK very closely!! If you SEE a very faint image of the desktop the units "switch-mode-power-supply" is in PARTIAL SHUTDOWN mode. (still has +5v or +3.3v to supply vga/lcd interface board) If you SEE NOTHING, then SMPS is in FULL SHUTDOWN mode. Get back to me, 12fixlouie with your SMPS flashlight evaluation and pay a visit to YOUTUBE fyi search and view video clips of "LCD monitor disassembly" and "LCD monitor repair" to see if DIY interests you! Also try www.ccl-la.com/badcaps.htm run by another tech on fixya nickname "buddymc" fyi. If this was of some help, rate this response on fixya. 12fixlouie aka louie12fix or lmistyrel @ aim.com
ok, if your computer is able to boot until you able to use it yet the screen is showing none yet working too, i suggest you change your data cable from the computer to the monitor. i once had a problem like that. it must have been damaged by high input of charge and burnt off though it did not show.
5 years old, lamps are good for about 50 000 to 60 000 hours of life you would have to do the math based on average number of hours per week/month and see where your are, several things to check initially are inside look for blown capacitors, you can find images all over the net Google "blown capacitor image" and you will see what to look for. Next could be inverter failure as they get old and work pretty hard. Last the ccfl lamps may be dieing of old age like the florescent lamps in buildings, they get burnt at each of the ends and have a hard time lighting up. let me know what you find.
our video driver probably was updated. You can try rebooting the PC
hitting F8 and going to "Last Known Good Configuration" You can also
try running a system restore to rollback to before you were having the
issue. Finally you can reboot hit F8 boot into safe mode, go to control
panel and system, go into the device manager double-click on the video
card driver and roll it back to the previous version.
I do not think it is the monitor's connection since you would have not initially seen the Window's splash screen.
